Hi Cole,

I have restarted all services on the Windows machine and checked with condor_config_val, that NTSSPI was there.

Hi Martin, I believe the authentication is choosing PASSWORD which is POOL password and thus trying as user condor (I do want to admit that the auth code is not my forte). When you added NTSSPI did you do a condor_reconfig? Without a reconfiguration

Hi Martin,

I believe the authentication is choosing PASSWORD which is POOL password and thus trying as user condor (I do want to admit that the auth code is not my forte). When you added NTSSPI did you do a condor_reconfig? Without a reconfiguration the Schedd will not have NTSSPI in its authentication list resulting in the client tool to still use PASSWORD authentication since the server side, i.e. the schedd, will pick the first matching option they both support.

Hi Cole,

Thanks for the hint, unfortunately it didnât help. What confuses me are these messages in SchedLog:

06/22/26 08:43:56 (pid:13476) WARNING: store_cred() for user username@WinDomainName attempted by user condor, rejecting

It seems as if the interactive invocation of condor_store_cred is carried out as user âcondorâ, not me.

Hi Cole,

condor_config_val -dump authentication_methods returns

# Configuration from machine: LP15-MAL1-CEM.dsone.3ds.com

# Parameters with names that match authentication_methods:

SEC_CLIENT_AUTHENTICATION_METHODS = IDTOKENS, PASSWORD

SEC_DEFAULT_AUTHENTICATION_METHODS = IDTOKENS, PASSWORD

SEC_WRITE_AUTHENTICATION_METHODS = IDTOKENS, PASSWORD

I had added the PASSWORDS methods only for Windows, but it seems it doesnât help in any way.

Hi Martin,

Some questions to help look into this:

1. What specifically are you running on the command line to store credentials?

2. Can you run the same command with the -debug:D_HOSTNAME option and share the resulting output (feel free to cleanse and/or send directly)?

3. You mentioned having a mixed pool. What OS are the Aps (submit hosts)?

ZjQcmQRYFpfptBannerEnd

We have recently upgraded our HTCondor cluster from 8.9 to 25.11. The cluster contains Linux as well as Windows machines. All authentication and authorization is configured to use IDTOKENS, which works fine under Linux. However when using the same approach on Windows any submissions fail and tell me, that I need to use condor_store_cred.

When I run condor_store_cred add I get an error âOperation failed because it is not allowedâ after entering the password.

SchedLog contains entries such as

06/17/26 11:58:38 (pid:25592) WARNING: store_cred() for user user@domain attempted by user condor, rejecting

I have to add that the DNS domain is not identical to the Windows domain name. I have tried adding both domains to the âALLOW_*â configurations, I have tried enabling PASSWORD authentication, but nothing seems to help. I have a token for user@winDomain in my tokens.d directory, which allows me to run e.g. condor_status. I tried the same with a token for user@dnsdomain, condor_status works here as well.

But condor_store_cred continues to fail in all these cases.

Any help would be very much appreciated.
